i've probably hit on something interesting that this person found motivation to plaster the thread with his stale jokes. whatever.
from here: http://en.wikipedia.org/wiki/Second
once upon a time there was a town called schilda in germany. during the 30-year war they were more lucky than others because the war somehow avoided them, but still they took some measures to secure their wealth. one of the worrying items was the bell from the church tower because the armies could take it for the brass, to make cannons. so they decided to sink the bell into the lake nearby. they loaded the bell onto a boat and rowed to the middle of the lake, where they threw it over board. one of the citizens was wise enough to mark the location of the bell so they could recoup it after the war: he cut a mark into the edge of the boat with his knife.
neither method is IMHO reliable to base any kind of sound knowledge of anything. in the case of time, a second is defined but not measured, rather arbitrarily. this is basically what motivated my original posting.

but here http://en.wikipedia.org/wiki/Time is something more interesting, a hint in the direction that time may be an "illusion", or rather, a device which the mind uses for purposes of orientation. the interesting part is here as quote, the rest is also interesting enough:
in any case, if we explore the possibilities of time being merely a device of the mind - an "illusion" - then one could achieve "time travel" not by any surreal technology but by way of understanding the nature of the illusion - rather, how and why the mind sets it up - and learning how to disregard it. (edited. was: ... the phenomenon better and making use of whatever attributes the phenomenon has).
thanks BTW for the link to the chronos/kairos PDF. don't have the quite right now, but the first 3 pages are interesting enough. the thing about simultaneous presents is something that i've noted since childhood, like this: is "now" for me the same as "now" for the guy over there ? he obviously lives in the same world, but his "time" is not the "same" as mine.

compare with the following tale:International second
Under the International System of Units, the second is currently defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom. This definition refers to a caesium atom at rest at a temperature of 0 K.

also, i obscurely remember from uni that the problem of time was mentioned in relation to processor design. it was the time of the 486 and people were starting to run into lots of problems related to synchronization between different components on the chip. one of the efforts around solving the problem of "clock syncronization" was about "clockless design" IIRC.Two distinct views exist on the meaning of time. One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. This is the realist view, to which Sir Isaac Newton [1] subscribed, in which time itself is something that can be measured.
A contrasting view is that time is part of the fundamental intellectual structure (together with space and number) within which we sequence events, quantify the duration of events and the intervals between them, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows", that objects "move through", or that is a "container" for events. This view is in the tradition of Gottfried Leibniz[2] and Immanuel Kant,[3][4] in which time, rather than being an objective thing to be measured, is part of the mental measuring system.
Many fields avoid the problem of defining time itself by using operational definitions that specify the units of measurement that quantify time. Regularly recurring events and objects with apparent periodic motion have long served as standards for units of time. Examples are the apparent motion of the sun across the sky, the phases of the moon, and the swing of a pendulum.
in any case, if we explore the possibilities of time being merely a device of the mind - an "illusion" - then one could achieve "time travel" not by any surreal technology but by way of understanding the nature of the illusion - rather, how and why the mind sets it up - and learning how to disregard it.
